When Dr. Mike Scanlon is called to serve as an army doctor in Afghanistan, he's acutely aware of the dangers he'll face and the hardships it will bring his wife Chloe and newborn baby. And deep inside, he doesn't think of himself as a hero, but a healer. However, in an ironic turn of events, as Mike operates on a wounded soldier in a war-torn country, Chloe dies at home in the suburbs, in an apparently freak household accident. Devastated, he returns home to bury her, only to discover that the life he left behind has fallen apart. He's a stranger to his baby girl, and his medical practice has downsized in his absence. Worse, he learns a shocking secret that sends him into a downward spiral.
